Hainbuch America Corp.

Founded in 1951 by Frida and Wilhelm Hainbuch, HAINBUCH GMBH has a long history of innovation beginning with the original quick change collet system, first patented in the USA in 1980. This invention has now been copied many times and is the de facto industry standard. Today, HAINBUCH boasts over 150 patents worldwide and continues to revolutionize the field of precise, adaptable and quick change collet chucks and workholding.

Recently Hainbuch introduced the G-211, a mandrel specifically designed for low volume, high mix production of gears. It is similar to our conventional turning mandrels, except it has a longer taper, allowing customers to have clearance for either their hob or their grinding wheel. We offer sizes to accommodate clamping diameters ranging from 20 mm up to 120 mm, and it uses our standard off-the-shelf bushings and end stops. The mandrel is also designed to accommodate three separate end stop positions. These features combine to allow manufacturers to quickly tool up jobs and to easily reconfigure the set ups between jobs.

Brands: •T-213 mandrel, which is commonly used in high production applications.
• G-211 mandrel designed for lower volume / higher mix production environments. Commonly used in gear cutting applications.
